Description
High-quality ABS/ESP control module and hydraulic pump from ATE supplied with a short section of wiring. This unit is intended for Citroën C5 II applications and is identified by the OEM and ATE numbers listed below. Ideal for professional workshops and experienced DIY technicians replacing a faulty braking control unit.
The assembly integrates an electronic control unit (ECU) with a hydraulic pump and valve block to modulate brake pressure during anti-lock braking (ABS) and electronic stability program (ESP) interventions. Proper function of this module is essential for controlled braking and vehicle stability, particularly under emergency or slippery conditions.
Common failure modes include electrical motor wear, internal valve blockage, corrosion of electrical connectors, moisture ingress, contaminated brake fluid, and physical damage from impacts. There is no fixed replacement interval; however, failures commonly appear after high mileage or when the vehicle has been exposed to corrosive conditions.
Replacement overview (general):
- Disconnect the vehicle battery before beginning any work to prevent electrical damage.
- Safely lift and support the vehicle, relieve any residual brake system pressure, and access the ABS unit (may require removal of undertrays or wheel arch liners).
- Carefully disconnect electrical connectors and brake lines; cap hydraulic lines to avoid contamination.
- Unbolt the hydraulic unit and control module from its mounting, replace with the new unit, and secure to OEM torque specifications (refer to the vehicle repair manual).
- Perform a full brake bleed using the correct procedure for the Citroën C5 II and clear fault codes with a diagnostic tool. Confirm operation and road-test under safe conditions.
